A printed circular disc monopole antenna with dual band-notched characteristic for UWB applications

In this article, a novel compact microstrip-fed slot antenna with dual band-notched characteristic is proposed. The proposed antenna consists of a circular patch and a multiple ground plane. By inserting two U-shaped slots to the circular patch and adjusting the dimensions of the slots, the antenna can reach a frequency band-width from 2.9 to 15.6 GHz for voltage standing wave ratio (VSWR) <; 2 and have two notched bands from 3.38-4.08 GHz and 5.15-6.15 GHz. The vital parameters of the proposed antenna are illustrated. The prototype was constructed and studied experimentally. Good agreement is obtained between simulated and measured antenna characteristics.
